摘要
It is proved that the number of F-q-rational points of an irreducible projective smooth 3-dimensional geometrically unirational variety defined over the finite field F-q with q elements is congruent to 1 modulo q. Some Fermat 3-folds, some classes of rationally connected 3-folds and some weighted projective d-folds also having this property are given.
